· JVASP-52901· Ca4H12Rh3

Ca4H12Rh3 is an experimental ceramic hydride compound containing calcium and rhodium, representing an emerging class of metal hydride materials under active research. This material family is being investigated for hydrogen storage applications and advanced energy systems, where the combination of earth-abundant calcium with catalytic rhodium offers potential advantages in hydrogen density and reactivity compared to conventional hydride ceramics. Due to its research status, Ca4H12Rh3 remains primarily of interest to materials scientists and engineers developing next-generation hydrogen technologies rather than established industrial applications.
